IMPROVEMENT IN FIRE-BOXES FOR STOVES AND RANGES.

The Schedule referred to in these Letters Patent and makin art of the same.

To all persons to whom these presents may come.-

Be it known that I, MARCUS L. HORTON, of the town and county of Windsor, of the State of Vermont, have invented a new and useful Improvement in Furnaces for the Combustion of Fuel, my said improvement being particularly applicable to the furnaces or fire-places of cooking-stoves or ranges, and I do hereby declare the same to be fully described in the following specification and represented in the accompanying drawing, of which- Figure 1 is a longitudinal section and Figure 2, a transverse sect on of a fire-place as provided with my said invention or metallic lining.

Figure 3 is a front elevation of it. Figure 4 is front view of part of -one of the; back plates of the chambered lining.

Figure 5 is a .front view of part of the intermediate or checkplate, for use with the said liningplates.

Figure 6 is a front view of part of the front or slat-ted the fuel, theair, during its passage through the said lining,labsorbing heat therefrom.

The lining rests on a channel or air-duct surrounding the grate, and is or may be surmounted with a lining of fire-brick, as represented at A in the drawing, and of the kin d described'in Letters Patent No.

97,29t 5, dated November 30, 186i), and granted to me. I

The two linings open into each other so as to allow air to pass from one into the other, andescape from the upper into the space over the fuel and there inter-mingle with the combustible gases, so as to ,promote or facilitate their combustion.

In the drawing the lire-place is shown at B, as provided with an air-channel or duct, 0, surrounding the grate D, and opening at its top into the slatted metallic lining E, which may be extended entirely or only partially around the ire-place, or it may be applied to opposite sides only of it, and be used with lire-brick or other linings, F,'disposed at its ends, as shown in the drawing.

The channel or air-duct O is to be provided with one or more openings or months, a a, furnished with doors or dampers, b b, and there may or. may not be a grate to the furnace or fire-place.

When a grate is used it may be furnished with solid bars, or it may have tubular ones, or it may be constructed like either of those described or represented in the aforesaid patent and the patent No. 74,536, granted to me February 18, 1868.

When without a grate, ahearth or plate would be substituted, in which case it may be madeor provided with means of discharging the ashes or waste of fuel, as occasion may require.

The'chambered metallic lining I compose, first, of a plate, 0, and a series of horizontal partitions or' flanges, (Z (Z (Z, having perforations, .e e e, in them, as shown; and, second, of another sect-ion or part, f, made with slats, g g, arranged like those of a common window-blind, with openings, 72/, between them,

and provided, when necessary, with stay-rib connections, 41.

These two sections, when arranged as shown in figs. 1, 2, 7 and 8, compose the chambered lining, which I usually make of cast iron, founding'each of the sections in one entire piece, or inone or more pieces.

There may be interposed between the two sections, what I term the check-plate G, formed as represented in rigs. 5 and 9, in which it is shown as having a series-of long horizontal slats, 7;, each slat having directly underneath it a rib or flange, b, which has a trapezoidal transverse section. I

These flanges, at their lower edges, rest on the tops of the slats of the front section, and serve to partially closc'or guard the openings of the slats, so as to prevent ooal-ashes or cinder-s from passing from the fuelspace of the fire-place into the air-chamber of the metallic lining.

Besides this, the check-plates serve to bring the air into better contact with the slats, and are advantageous in other respects.

The chambered metallic linings, when combined with the fire-brick linings, as represented, should open at top into the lower part of the saidfire-brick linings.

I claim- 1. The combination of the series of slats g, arranged as desoribed, with the back-plate e, and its series of perforated partitions d, all being arranged as and for the purpose of making a metallic lining for a furnace, as specified. v

2. The combination and arrangement of the slatted check-plate G, made as described, with the series of slats y, arranged as set forth, and with the back plate 0, and its series of. divisional perforated partitionsd, all being arranged as explained.

, 3. The combination and arrangement of the firebrick lining A, as set forth, with the metallic lining, as composed of the series of slats g, and the back-plate .c, and its perforated partitions d, or of such, and the check-plate" G, as described,'arranged MARCUS L; HORTON.

as explained.
